Deuteronomy 8:11-20

“Beware that you do not forget the LORD your God by not keeping His commandments and His ordinances and His statutes which I am commanding you today; otherwise, when you have eaten and are satisfied, and have built good houses and lived in them, and when your herds and your flocks multiply, and your silver and gold multiply, and all that you have multiplies, then your heart will become proud and you will forget the LORD your God who brought you out from the land of Egypt, out of the house of slavery. He led you through the great and terrible wilderness, with its fiery serpents and scorpions and thirsty ground where there was no water; He brought water for you out of the rock of flint. In the wilderness He fed you manna which your fathers did not know, that He might humble you and that He might test you, to do good for you in the end. Otherwise, you may say in your heart, ‘My power and the strength of my hand made me this wealth.’ But you shall remember the LORD your God, for it is He who is giving you power to make wealth, that He may confirm His covenant which He swore to your fathers, as it is this day. It shall come about if you ever forget the LORD your God and go after other gods and serve them and worship them, I testify against you today that you will surely perish. Like the nations that the LORD makes to perish before you, so you shall perish; because you would not listen to the voice of the LORD your God.
